  • Vehicle steering system
    Patent number: 12122462
    Abstract: A vehicle steering system includes a rack shaft, a pinion shaft, a housing including a rack shaft receiving portion and a pinion shaft receiving portion, and a cover member disposed above the pinion shaft receiving portion. A part of the pinion shaft projects upward from an upper end opening of the pinion shaft receiving portion. The cover member includes a hood portion and an annular side wall portion. The pinion shaft is inserted through the hood portion. The side wall portion includes a valve portion capable of coming into abutment with an outer circumferential surface of the pinion shaft receiving portion.

  • Powdery particle conveying system and roots blower operating method
    Patent number: 7114889
    Abstract: A powdery particle conveying system is provided in which electric power consumption can be saved when powdery particles are conveyed by use of a roots blower. In the case where the powdery particles are conveyed to a reservoir tank near the roots blower, the frequency of a power source of a roots blower driving motor is reduced, thereby reducing an output of the roots blower. In contrast, in the case where the powdery particles are conveyed to a remote reservoir tank, a voltage of a commercial frequency is applied to the motor.
